Jaw, Edentulous Clinical Trial

Official title:
An Open, Prospective, Multicenter Study to Evaluate Treatment of Edentulous Upper Jaws With an Implant-Supported Prosthesis Retained by Astra Tech Dental Implants, Fixture Micro-Macro in Patients With Poor Bone Quality

Clinical Trial Summary

The primary objective of the study is to evaluate the long-term survival rate of individual implants and prostheses when treating edentulous upper jaws of poor bone quality with Fixture MicroThread™ (Micro-Macro).

Clinical study recruitment was stopped in year 2000 due to a decision to modify the product under study. This was a result of feedback regarding the subjective feeling during the installation procedure. There were no safety concerns w/r to the study products. Patients already included and treated in the study were monitored for the full duration of the study in accordance with the clinical study protocol.
